Description

The field model relates to the field of energy and can be used in heat supply systems

There is a known scheme of a heating boiler room 11, in the rutor part of the water after chemical water treatment is supplied by an electric pump to the deaerator. After deaeration, water is drawn in by an electric pump and fed to steam boilers. The remainder of the water after chemical water purification is supplied by another electric system to the heating network.

The ycTaHOBKaj boiler room described in 23 was selected as a prototype. Water is supplied through the heater to a two-stage chemical water treatment unit and then distributed along two technological lines: boiler supply line and consumer supply line. Each line includes a deaeration head connected directly to the corresponding battery capacity, as well as a discharge device for an electric pump. One willow of electric pumps delivers de-aerated water in a boiler; another - deaerated and heated water in a heat exchanger - to a heating network.,,

The above analogue, like the prototype, contains the electron probe of the sucker and bulky heat exchangers. The presence of electric pumps determines the use of appropriate electrical equipment and increases the likelihood of failure of the system as a whole. On the other hand, in the event of a sudden interruption in the supply of electricity, the output of the steam boiler may occur.

The power supply j is large and unreliable in operation.

The utility model is based on the task of creating a reliable boiler house autonomous from the main power line of the boiler plant, with minimum dimensions and dimensions, up-front costs and high maintainability.

This task is solved by the fact that in a boiler installation that includes a boiler, a chemical water treatment unit, to the output pipes of which the boiler feed line and consumer supply line are connected, the boiler feed line contains the first heat exchanger, the first output pipe of which is connected to the first deaeration head, the first battery capacity, the first discharge device connected to the boiler with the boiler, the consumer supply line includes a second battery capacity, a second heat exchanger connected by the second outlet pipe with the second deaeration head, and the second outlet pipe with the second discharge device, new is that the discharge devices of both lines are made in the form of the first and second steam-water injectors, the third and fourth steam-water injectors are introduced separately, and the third injector is installed between the first battery capacity and the second outlet pipe of the first heat exchanger, the second inlet pipe of which is connected about the outlet pipe of the first deaeration head, four rty injector uotanovlen of software. the possibility of supplying water to the heating system and is located on the outlet pipe of the second battery capacity, the inlet of which is connected to the second injector, the outlet

the second decontamination head is connected oo to the second inlet pipe of the second heat exchanger

In the Figure, the principal ohema of the inventive boiler unit is provided.

The installation contains a chemical water treatment unit Ij the outlet pipes of which are connected to the boiler supply and consumer supply lines. The nut feed line crashes: the first heat exchanger 2, the first outlet pipe of which is connected to the first deaeration head 3 connected by a pipe to the second inlet pipe of the first heat exchanger g, and also the first storage tank 4, the first steam-water injector 5 and the plug-in 5. connected in series : a second heat exchanger 7 connected by a first outlet to a second deaeration head 8, which is connected by a pipe to a second inlet to a second heat exchanger Nick 7 has a second outlet pipe through a second steam-water injector 9 connected to a second battery capacity 10. In the boiler supply line, a third steam-water injector 11 is installed between the second output pipe of the first heat exchanger S and the first battery outlet 4, and in the consumer supply line, at the output pipe of the second battery capacity 10, a third steam-water injector IS is installed, which supplies water to the heating system. All steam-water injectors and deaeration heads are connected by pipelines to the distributing collector of the boiler.

Each technological line additionally contains, at each decontamination head, a corresponding block 13 and a block 14 for maintaining its thermophysical parameters (maintenance is ensured, among other things, by removing the vapor-air mixture and the naked eye) J and each battery capacity is equipped with a block 15 and a block 16 for regulating and maintaining pressure in capacities. Blocks 13-16 Taime connected to the respective pipelines on the distributor of the boiler 6.

Installation works as follows.

The initial start-up of the installation is carried out using a starting diesel generator

In the process, the water flowing out from the chemical water purification unit 1 enters the boiler feed line to the first heat exchanger 2. It is heated in it to the required temperature and flows to the first deaeration head 3. The de-aerated water is supplied to the second inlet pipe of the first heat exchanger 2, where it is cooled, to the required temperature and is taken by the third injector 11 with subsequent supply and heating to the first battery capacity 4. Leaving the battery capacity 4, water is taken and heated by the first injector 5 with subsequent odachey the boiler 6, and converted into steam enters through potebitelyam distributing manifold.

Another part of the water after the chemical water purification unit 1 is supplied to the technological line for supplying consumers. Having passed the second heat exchanger 7 ,. where it is heated to the required temperature, it enters the second decontamination head 8 and then to the second inlet pipe of the second heat exchanger 7. The water cooled in the heat exchange is taken by the second injector 9., which heats it to the required temperature and delivers it to the second absorber tank 10, then it is picked up by the fourth injector 12 and

- 4 is supplied s heating system.

The steam required for the injectors and blocks 13-15 comes from the distributor of the boiler 6.

In this way, VZMVEV some elements on the other, the introduction of new elements and new connections between them provides new installation properties and achievement of the task. Water circulation in the proposed scheme is controlled by the steam produced by the boiler, and does not need in power from the power line. In addition, the lack of power supply equipment and electrical connections increases the reliability of the installation. Replacing bulky heat exchangers and electric pumps with injectors reduces the overall dimensions of the installation and increases its maintainability.

The boiler plant will find application in the region}, in which electricity is absent or not guaranteed.

The installation can be performed in a block mobile version and used in special conditions: liquidation of consequences of emergency incidents, military operations. 1.Ionik A.A. to others.
